A+ Click helps students become problem solvers.
Free, without ads, no calculators, and without signing-up.
The website features a graduated set of 15,000+ challenging problems for students in grades one through twelve, starting from the very simple to the extremely difficult.
The questions are based on the Common Core Standards in Math and go beyond by adding hundreds of meaningful practical problems and brainteasers.
The questions concentrate on understanding, spatial reasoning, usefulness, and problem solving rather than math rules and theorems.
The problems include a short description and an illustration to help problem solvers visualize the model.
The problems can be solved within one minute and without using a calculator.
The tests adapt to student ability.
To progress to a higher level, you must correctly answer five consecutive questions.
Younger kids in grade 1 through 5 have two chances to get it right.
If you correctly answer 16 questions, the system suggests you enter the competition (click on in the left menu).
The self-study learning site includes game elements: star scoring system, cheering sounds for young kids, statistics (click on in the left menu), and a Leaderboard.
The Leaderboard shows the best performers of the last 10 days.
Igor Kokcharov launched the project in 2010. Leslie Green joined the project in 2015 revising all the questions, adding meaningful answers and many new original problems.
Igor explains in the A+Click blog:
"When I was a young boy, I studied mathematics in school and also on my own using Martin Gardner's puzzle books.
Now, as an adult, I am eager to help children throughout the world who are in the same position that
I was in as a child to discover interesting, practical, and challenging math and logic puzzles."
